What are the constant parameters in Charles' gas law? I know the changing paramters are temperature and volume. I'm not sure about the constant though.

Question

jfraser · Answer

when working with gases, there are 4 properties: pressure, volume, temp, and quantity (moles). The simple gas laws deal with 2, while leaving the other 2 constant. If Charles' Law changes temp and volume, what 2 stay constant?

Pressure and quantity! :O

If you know the ideal gas law, you can actually derive all of the other gas laws with a little algebra

We havn't gotten into ideal gas laws yet. We have to fill in the blanks of the different gas laws right now.

jfraser · Answer

well when you get to it, the IGL is more useful than knowing all the separate ones, IMO

anonymous · Answer

Ideal gas law is given by PV=nRT P is pressure V is volume and n is moles. R is the gas constant and T is temperature in Kelvin.  You could derive the other gas laws from here and see the relationship between the given quantities. For example it's obvious in this equation that pressure is inversely related to volume when the rest of the quantities are constant.
